The Silent King's Secret.... HOW TO BEAT !? *spoilers*

[THE HOUND FROM SWAMPS]

ok so im on The Silent King's Secret and im getting so sick of how long is taking. im crushing literally oblesk after monolith after teseract vault and annhilation barges. thank god i stocked up on death scythes (flying unit w/e) and now they're all like lvl 10. its been over 10 turns and a few hours now and my eyes are tired.

is my game bugged? does this normally go on for so long? its only medium difficulty and i want to beat this last chapter

It lasts 20 turns. It should tell you that in the objectives.

It ends when you destroy last mission enemy grey necron attackers.

They will travel towards your base, but bad luck if last enemy obelisk/monolith is opposite side of the map.

Just hit next turn button.

Ok thanks, all it says is "defeat invading enemy units" and keep control of the control module thing. No turn count down/how long it lasts

Then it's 20 turns of spawn (one wave every 2 turns and 10 waves).
So 20 turns minimum + the time you need to kill all the units spawned by the quests.
